Answer: C

Step-by-step explanation:

A sodium-potassium pump moves sodium from an area of low concentration to an area of high concentration, or against their concentration gradient. They do this with the help of phosphate, which is released when an ATP molecule splits. The diagram is missing reference to these ATP molecules, so the correct answer would be C.

Hope this helps!
